Now, that's not to say I disagree that it needs to be better discovered, and it is certainly not an argument or plea that this be left alone. For new users the fantastic look of this needs sacrificed to some degree.
Perhaps something such as this would be sufficient? I realize it's super simplistic and it doesn't address the actual problem of making it clear those fields are editable, but I do wonder if it might be enough or would it be just as ignored as the help/wiki/forum search?
EDIT: I suppose I should have left the Nav Panel open as otherwise the IP looks extremely long and that ? icon looks lost to the right. It could be kept in line with the end of the attributes table. Granted it's in the exact same position as the orange down arrow on Raw View in the picture above.
